Some information:

this is not how it works for me on i3-12100F (14.1-p2):

for cpu in $(seq 0 7); do sysctl dev.hwpstate_intel.$cpu.epp; sysctl dev.cpu.$cpu.freq; done
dev.hwpstate_intel.0.epp: 50
dev.cpu.0.freq: 1450
dev.hwpstate_intel.1.epp: 50
dev.cpu.1.freq: 1165
dev.hwpstate_intel.2.epp: 50
dev.cpu.2.freq: 1248
dev.hwpstate_intel.3.epp: 50
dev.cpu.3.freq: 1152
dev.hwpstate_intel.4.epp: 50
dev.cpu.4.freq: 799
dev.hwpstate_intel.5.epp: 50
dev.cpu.5.freq: 799
dev.hwpstate_intel.6.epp: 50
dev.cpu.6.freq: 799
dev.hwpstate_intel.7.epp: 100
dev.cpu.7.freq: 799

(I have manually changed epp for the last core).
